摘要
利用快中子透射法检测管道油垢,其实验装置由241Am-Be中子源、ZnS探测器和BH1224多道谱仪组成。用石蜡仿油垢,铁板仿管壁。实验结果表明,透射率倒数的对数与标定石蜡厚度间具有很好的线性相关性,相关系数为0.999 6。在本实验装置和条件下,测厚准确度为0.6 mm。
The principle, experiment and conclusion on the grease stain measurement using fast neutron are reported. The experiment equipments consist of ^241Am-Be fast neutron source, ZnS detector and BH1224 muhichannel spectrometer. Paraffin is used instead of real grease stain. Steel plates are used instead of pipeline. The results of the experiment indicate that there is a good linearship between the logarithm of the reciprocal of the neutron transmissivity and the paraffin thickness. The measuring accuracy of the paraffin thickness is 0.6 mm in this experiment.
